Mansfield, Ohio, assignors to Kingston Products Corporation, Kokomo,Ind., a corporation of Indiana Filed Aug. 31, 1960, Ser. No. 53,151 19Claims. (Cl.74-128) This invention relates generally to timers, such asmay be used to control coin-operated laundry machines, and morespecifically to improved coordinating structure incorporated thereinwhich renders the timer assembly responsive to a plurality of manualmovements, such as may be obtained by insertion of a plurality of coinsuccessively in the coin mechanism thereof.

Although the principles of the present invention may be included invarious devices, a particularly useful application is made in a timer ofthe type that is employed with a coin mechanism, whereby a plurality ofcoins must be successively inserted therein to initiate the operation ofthe timer, which thereafter completes a program, such as the operationof a dry cleaning machine.

Mechanisms have previously been provided by which a timer is renderedresponsive to the insertion of a coin in a coin mechanism. Ordinarily,only a single coin is needed to place such mechanism in operation, and acoin mechanism is employed of a size which accommodates the desireddenomination of coin. Thus a quarter, a half-dollar, or the like may beemployed to initiate machine operation. Where two coins have beenneeded, such as two dimes or two quarters, it has been known heretoforeto provide two coin mechanisms mechanically coupled together, and whenboth such ganged coin mechanisms are released by insertion of coinstherein, they coact as a single mechanism to initiate operation of thedevice.

With the advent of inflation, the need for two coins has become moreprevalent, and it is apparent that the use of two or more ganged coinmechanisms raises the cost of the resulting structure considerably,multiplies the amount of mechanism which might malfunction, increasesthe panel space required to support the coin mechanism, and the like.

Where operation ofa dry cleaning machine is to be initiated in responseto operation of a coin mechanism, several larger denomination coins willbe needed, for example three or four quarters. Under these conditions,duplication of coin mechanisms to accommodate large denomination coinsfor that type of operation becomes bur ensome, ineificient, andexpensive.

In accordance with the principles of the instant invention, there isprovided a novel coordinating or drive mechanism for the timer assemblyitself which is responsive to movement of an external actuating member,such as may be carried by a coin mechanism. The novel coordinatingmechanism of this invention is responsive to a plurality of movements ofthe actuating member in such manner that a preselected number of suchmovement are required to initiate timer operation. Stated otherwise, ina device of the type described where the instant invention is provided,a quarter may be inserted in the coin mechanism and the coin mechanismoperated.

The novel coordinating mechanism is responsive to such operation andmechanically remembers that one coin has been apparently inserted. Suchoperation is repeated until a preselected number of operations hasoccurred, for example three, the third coin then being effective toinitiate operation of the timer control mechanism.

Accordingly, it is an object of the present invention to provide a novelangular drive mechanism.

Another object of the present invention is to provide a novel connectingand coordinating means for a timer,

, A ice by which the timer is rendered responsive to an externalactuating force.

Yet another object of the present invention is to provide a drivemechanism for a timer assembly such that the drive mechanism will setthe timer in a starting position only after a predetermined number ofactuations of said drive mechanism.

A still further object of the present invention is to providecoordinating means for acting between a coin-receiving mechanism and atimer mechanism to be controlled thereby, such coordinating mechanismbeing responsive to a plurality of operations of the coin mechanism toinitiate timer operation.

-Many other advantages, features and additional objects of the presentinvention will become manifest to those versed in the art upon makingreference to the detailed description and the accompanying sheets ofdrawings in which preferred structural embodiments incorporating theprinciples of the present invention are shown by way of illustrativeexample.

As shown in the drawings:

The principles of this invention are particularly useful when embodiedin a coin-operated timer device assembly 11 such as shown in FIGURE '1.The device 11 includes a rugged case 12 which supports a conventionalcoin mechanism 13 having a manually operated slide 14 in which a singlecoin is received.

The device 11 further includes a timer assembly 15 driven by a motor 16supported thereon. The timer 15 is secured to the case 12 by anyconvenient means. The details of the timer mechanism 15 do not form apart of the instant invention and the timer preferably includes anoutput shaft 17, herein also referred to as a function control shaft,which is rotatable by the motor 16 in the direction indicated by thearrow in FIGURE 1. An example of the timer 15 is shown in the UnitedStates patent to Constantine No. 2,703,347. In timers of this type, theshaft is rotatable for 360. A series of cam operated switches areprovided to control the program of the device to which the timer 15 iselectrically connected. The timer is so internally Wired that when theshaft 17 reaches a predetermined position, referred to as a finishposition, power to the motor 16 is interrupted. To restart the timer, itis necessary that the shaft 17 be advanced in the same direction to astarting position at which'the motor circuit is reestablished, and fromwhich position the timer 15 will be operated by the motor 16 to thefinish position.

Since the motor 16 is powered through one of the switches within thetimer 15, it can be seen that the total duration of the timing programis partly dependent on the angular distance that the shaft 17 isinitially manually advanced at the start of the program. Therefore, theangu lar distance between the starting and the finishing positions ofthe shaft 1'7 is less than 360. The shaft 17 of the timer mechanism isdisposed in offset relation to the path in which the operating means orslide member 14 of the coin mechanism 13 may move.

To connect the movements of the coin mechanism slide 14 with the timershaft 17, and to coordinate the initial manual movement of the shaft 17with the movements of the member 14, there is provided a one-way angulardrive mechanism generally indicated at 18 in FIGURE 1, and shown inenlarged detail in FIGURE 2.

As seen in FIGURES 1 and 6, there is provided a drive means or actuatingmember 19, here comprising a drive arm connected to the slide 14- andreciprocable therewith in a path, the drive arm 19 having a cam surface20 directed in the direction of reciprocation. The cam surface 2% isillustrated herein as being generally arcuate and concentric with theshaft 17 of the timer 15.

As best seen in FIGURES 2 and 3, the drive mechanism 18 includes a shaft21 rotatably mounted at one end on a bracket arm 22, the shaft 21 beingsupported at its opposite end by a connector means 24 which in turn isrotatably supported by a bracket arm 23. A setscrew 25 renders the shaft21 and the connector means 24 corotatable, while a slot and pinarrangement generally indicated at 26 renders the connector 24 and theshaft 17 corotatable. It is thus apparent that the shaft 21 couldcomprise an integral extension of the timer shaft 17. Thus the shaft 21has a rotary drive connection with the device 15.

On the shaft 21, there is provided rotatably supported control means oneportion of which is illustrated in this embodiment by a first rotatablysupported means 27, and another portion of which is illustrated in thisembodiment by a second or further rotatably supported means 28. Thefirst rotatably supported means 27 includes two members 29, 30, themember 29 being a radially extending portion which is disposed in thepath of the drive arm 19. The member 29 thus comprises a support platefor a roller 31 which is engaged by the cam surface 20 of the drive arm19. The other member 3 4 is a base plate which has a stop portion 32engageable with a stop or abutment surface 33 on the bracket arm 22. Themember is staked to a hub 34, there being a non-circular portion of thehub 34 extending through a non-circular opening in the member 3%. Themember 29 may be angularly adjusted with respect to the member 3% bypivoting about the hub 34, and to this end is slotted as at 35 toreceive a screw as for locking the members in a selected position. Thisadjustment is particularly useful for selecting or adjusting the lengthof the cam surface 2% which may engage the roller 31. A return spring 37acts between the bracket arm 22 and the member 30 to bias the firstrotatably supported means 27 in such direction that the stop portion 32is normally engaged with the stop 33. Thus the means 27 normally isstationary and is disposed as shown in solid lines in the variousfigures. In some installations, the effective length of the slide 14 isquite substantial, and there is a danger that the drive arm 19 will slipoff, namely radially outwardly of the roller 31. To avoid such anoccurrence, there is provided, as best seen in FIGURE 1, a rigid guide353 which is disposed adjacent to the roller 31, and which is slidablycngageable with the drive arm 19 to limit the amount which the drive armmay move radially away from the rotational axis of the means 27.

Referring again to FIGURE 1, it is now apparent that as the drive arm 19is manually moved to the right, the cam surface 281 engages the roller31 and effects rocking of the means 27 as a unit about the shaft 21 inthe direction of rotation of the shaft 17, and effects furthertensioning of the spring 37 which returns the means 27 when the drivearm 19 is retracted. Thus the rotatably supported means 27 may berockably driven in response to manual movement of the drive arm 19.FIGURE 6 illustrates the movement of the drive arm 19 to the right bywhich the roller 31 is engaged by the cam surface 20 and rocked with themeans 27 on the shaft 21. The surface 29 which is directed toward theroller 31 includes a straight portion 20a which extends parallel to thedirection of movement of the actuating member 19. Once the raightportion 20a is engaged by the roller 31, as shown in broken lines inFIGURE 6, the means 27 is rocked no further. However, the straightportion Ztla allows increased, variable, or excess travel of the coinslide 14 to occur without causing further angular advancement or rockingof the means 27, since the portion 20:: holds the roller 31 in theposition shown.

In like manner the second or further rotatably supported means 23 issupported on the shaft 21 and to this end includes two members 39, 49carried on a hub 41. The member 39 has a non-circular openingcorresponding to a non-circular portion of the hub 4-1 of likeconfiguration, the member 39 and the hub 41 being staked together forcorotation. The member 4t) is rotatable about the hub 41 and is securedby a screw 42 to the member 39 for corotation about the axis of theshaft 21. To this end the screw 42 is received in one of a number ofholes 43, the particular hole 43 used being selected to determine therelative angular relationship between the members 39 and 4% for apurpose presently to be explained.

The member 39 has a plurality of peripherally disposed abutments 44,best seen in FIGURES 4 and 5. Means are provided which act on the means2d to prevent a reverse rotation thereof, namely to prevent a rotationopposite to that of the shaft 17, such means in the embodimentcomprising a resilient blade 45 which is successively engageable withthe various abutments 4 5.

The member 30 of the normally stationary means 27 is provided with aresiliently yieldable indexing finger 4-6, best seen in FIGURES 4 and 5,the finger 46 comprising, in this embodiment, a portion of a bell crankpivotally secured as at 47 to the member 30, a spring 48a providing abias for pivoting the finger 46 about its pivotal axis and toward theperiphery of the member 39. Each rocking movement of the normallystationary portion 27 includes an increment in the direction of thearrow in FIGURE 4, which thus causes a like movement of the secondsupported means 28 which includes the member 39, the member 39 thusbeing advanced in a single direction by the indexing finger 46 acting onone of the abutments 44, the rocking of the means 27 thus effecting anangular inrement of one-way movement of the means 28.

A predetermined one of the angular movements of the means 28 istransmitted to the shaft 21 by means of a lost motion connection. Asbest seen in FIGURE 2, the lost motion connection includes a shoulder 48illustrated as being an integral portion of the member 3?, and ashoulder 49 illustrated as being an integral portion of the member 4%.Between the shoulders 48 and 49, there projects a radially extendingmember 5%, here illustrated as being a pin corotatably carried by theconnector means 24. Each of the shoulders 48 and 49 is radially offsetfrom the axis of the shaft 17 and extends in a generally axialdirection. Thus the shoulders 48, 49, and the pin 5% coact to provide anangular lost motion connection between the means 28 and the shaft 117.The angular amount of such lost motion is determined by the angulardistance between the shoulders 43 and 49, within which the pin St) isdisposed. This space or angle may be adjusted by repositioning the screw42 into one of the other holes 43.

Normal rotation of the shaft 17 by the motor 16 causes the pin 5-9 toengage the shoulder 48 and to rotate the means 28 with the timermechanism 15'. A spring 51 acts between a point which is corotatablewith the timer, illustrated as being the pin 59, and a second pointwhich is corotatable with the second means 28, here illustrated as beingthe axial projection from the member 39 on which projection the shoulder43 is located. The spring 51 thus biases the pin 56 into engagement withthe shoulder 43.

When the second means 23 is advanced an increment by the means 27 asalready described, the shaft 17 and pin 50 remain stationary, but themeans 23, including both shoulders 43 and 49, rotate by a like angularamount, thereby placing further bias on the spring 51, without effectingrotation of the shaft 17, the resistance to movement thereof beingobtained from the timer 15.. When the drive arm 19 is retracted, thespring blade .45 acting on one of the abutments 44 maintains the angularincrement of movement which has been imparted to the means 23 so thatthe means 23 does not return. If the mechanism is to be so adjusted thatone coin will start the timer, the shoulder 49 is reset so as tominimize the gap between the shoulders 48 and 49. However, the inventionis used to best advantage when the gap between the shoulders 48 and 49is equivalent to a plurality of angular increments so that the second,third, fourth etc. coin must be inserted, or so that the second, third,fourth etc. movement of the drive arm 19 must be imparted before theshoulder 49 engages the pin 5th to drive the same in the direction ofnormal shaft rotation with sufiicient force to overcome the internalmechanical resistance in the timer 15, thereby advancing the timer toits start position.

Thus the angular lost motion means or connection between the rotatablemeans 28 and the shaft 17 ultimately effects a driving rotationalengagement therebetween, but does so only after a predetermined numberof rocking movements of the first means 27 which effects a like numberof angular increments of movement of the means 28. Thus the variousabutments 44. are spaced about the rotational axis by an angle withrespect to each other which is less than that of the effective angle ofthe lost motion connection, by which each increment of angular movementof the means 2% is less than the angle of the angular lost motionconnection.

It is to be understood that the details by which this invention has beendisclosed are exemplary, and that the invention may be embodied in otherstructures. Referring to FIGURES 7 and 8, a slightly modified form ofthe instant invention is disclosed. in these figures an angular drivemechanism 52 includes a shaft 53 rotatably supported at one end in abracket 54 and having a connector means 55 at the other end thereofwhich is rotatably supported in a bracket arm 56, the connector means 55being corotatably coupled to the timer shaft 17 as described before. Afirst rotatably supported means 57 includes two members 53, 59, one ofwhich is staked to a hub 69, and the other of which is adjustable withrespect thereto by means of a screw and slot arrangement 61. The member59 has a radially extending portion on which a roller 31 is carried forcooperation with the drive arm 19 as already described. The member 59also has an indexing finger d2 pivoted at 63 thereto and which finger 62is re siliently biased by a spring 64 into peripheral engagement withone of a series of abutments 65. The spring 64 is secured at its otherend to a portion of the member 59, and the means 57 as a whole isresiliently biased by an additional spring which acts between the meansd7 and a portionof the bracket which has been removed for clarity ofillustration. The member 58 includes a stop portion 67 which isengageable with a stop as forming a part of the bracket 54-.

The mechanism 52 further includes a second rotatably supported means 69including a member 70 having the abutments 65 and a second member 71adjustably secured thereto by screw means 72. The members 7i) and 71 arerespectively provided with shoulders 73, 74 between which a pin 75 isdisposed to form an angular lost motion connection between the means 69and the shaft 17, the pin 75 being corotatably secured to the connectormeans 55. A spring 76 acts between an ear 77 on the member 70 and apoint corotatable with the shaft 17. Reverse rotation of the means 69 isprecluded by means of a spring blade 78, the distal end of which issuccessively engageable with the various abutments 65.

The operation of this embodiment is substantially the same as that whichhas already been described. By means of the adjustment locked by thescrew 61 the relation between the roller 31 and the drive arm 19 may beestablished. It will be noted that the indexing finger 62 thus also isadjusted, whereas in the earlier described embodiment, the correspondingindexing finger is carried by the member which has the stop portion. Thestructure, function, and adjustment of the means 69, including the lostmotion connection, is substantially identical to that illustrated in thefirst embodiment.

, Referring now to FTGURES 9 and 10, there is shown an additionalembodiment of the invention, which differs from the previously describedembodiments primarily in that the adjustment features have been omitted,and that the indexing finger is not pivotably supported. By the omissionof these features, a somewhat simplified form of the invention isprovided, generally indicated by the numeral 79. This embodiment alsoincludes a rotatable shaft 80 supported at one end by a bracket 31 forrotation, and at the other end by the timer shaft 17 acting throughconnector means 82 which is pinned to the shaft 80 by a pin 83 forming apart of the lost motion connection. The mechanism 79 includes a firstrotatably supported means generally indicated at 84-, which is reelableon the shaft 80, and a second or further rotatably supported means 85which likewise is rotatably supported on the shaft 8t), and which has anangular lost motion connection therewith.

As best seen in FIGURE 9, the first rotatably supported means 84 has twoportions, one of which is indicated by the numeral 86 which supports theroller 31 in radially extending relation to the shaft St), and the otherof which is indicated by the numeral 87 which is a stop portion whichengages a stationary stop 88. Bending of the stop 88 atfords a degree ofroller adjustment. A return spring 89 biases the means 84 intoengagement with the stationary stop 88. The roller supporting portion 86and the stop portion 87 form a part of a n1ember 90 which is secured toa hub 91, which is held in position between a shoulder on the shaft 39and a snap ring 92. A resiliently yieldable indexing finger 93 isriveted as at 94 to the member 90, one end of the finger 93, indicatedat 95, being bent over to prevent angular movement about the rivet 94,and the other end, indicated by the numeral 96, being engageable witheach of a series of abutments 97 on the second rotatably supported means85. The end 96 of the indexing finger 93 yields in an axial direction inresponse to the next abutment 97 when the finger 93 is being returned bythe spring 89.

The second or further rotatably supported means 85 includes a member 93having a series of peripheral abutments 99 engageable by a blade spring109 to maintain the angular position of the rotatably supported means 85during return rocking of the first rotatably supported means 84. Themember 100 is secured as by staking, to one end of a hub 191, a stopplate 102 being secured as by staking to the other end thereof. The stopplate Hi2 has a pair of axially directed or extending projections whichjointly define a pair of shoulders 103, 104 between which the pin 83 isreceived to define the lost motion connection between the means 85 andthe shaft 80. A spring 1% acts between a point corotatable with thetimer shaft 17, namely the pin 83, and a point corotatable with themeans 85, namely an ear 107 on the member 98. Thus the means 85 includesportions comprising abutments for indexing, and other portions whichdefine shoulders. The extensions which define the shoulders may be bentto afford a degree of adjustment. Since the shoulders N3 and 194 arecorotatable with respect to the member 98, it is apparent that either orboth of the shoulders 103, 104- could be integral therewith as shown inFIGURE 5. However, there is an advantage to having at least one of theshoulders 163, 104 on the separate member or plate M2. It is apparentfrom the two preceding embodiments that abutments 9'7, 99 may beprovided in greater quantity than that illustrated in FIGURE 9. It isalso apparent that the degree of adjustment to be afforded by bendingthe fingers which carry the shoulders 103, 164 would not be sufficientto alter the number of rocking actuations of the first rotatablysupported means 84 needed to initiate angular movement of the shaft 17.Thus in the manufacture of this device, it is advantageous that themember 98 be provided with a substantial number of abutments forsubsequent asembly with any one of several stop plates 162 which have anincluded angle, or which provide with the member 98 an included angle,of such magnitude as to render the desired number of abutments usable.

The operation of this embodiment is thus similar to that alreadydescribed.
